Adding Additional Fields To Opencart DB and display of field

I need somebody to create a new field which is stored against a customer record within the opencart ecommerce my sql db, this field being our internal account number. I also want this field to show in the followng areas: Open Cart Orders Dashboard Last Ten Order Screen And Order Detail Screen. Also this field must not be able to be modified by the customer so its only viewable in the backend. Also I would like the source code and instructions on how this change was done. And would also like an opencart specialist to help me with various development for a new website. So if the desired skills are proben for this project there will be lots more opencart db configuration and implementation changes in the near future.
